Study of the Effects of Competitive Basketball upon the Physical Fitness of High School Boys as Determined by McCurdy-Larson Organic Efficiency Tests

Abstract

This methodology study was to determine if testing subjects on a specific day of four phases of the menstrual cycle would yield results which would be comparable to testing subjects on each day of the corresponding phases of the cycle and if the test results of one cycle would be comparable to those of two consecutive cycles. A statistical comparison of the mean scores for a specific day of each phase of the cycle and the mean scores for the average of all days for each phase of the cycle was made for pulse rate before exercise, pulse rate after exercise, and the difference in the pulse rate before and after exercise, or pulse rate increase. None of the t ratios obtained were significant. A statistical comparison was also made for the mean scores for two mentrual cycles for pulse rate before and after exercise, pulse rate increases, weight, and temperature. None of the t ratios were significant. It was concluded that testing subjects on a specific day of each of four phases of one menstrual cycle would be a satisfactory testing procedure.
